I have a 09 KTM 450EXC that I am having trouble getting to idle. Today was the first time I tried to get the bike to run with some success.
I can get it to start, only with the choke on. It will let me take the choke off, but if I do not give it some gas it will die. Will not idle at all.
Also I noticed that if I blip the throttle it will back fire when the rpms come back down.
So far I have only drained the tank, put fresh gas in and drained a bit more. I did see a nice little white chunk come out...
So is this a case of I will have to pull the carb and clean it out good? Seafoam or the like?
Suggestions???
